The Mexican government says a man whom U.S. authorities shot with a stun gun at a San Diego County border crossing is unconscious and in serious condition.

The Mexican consulate in San Diego said in a statement Saturday night that agents from the Border Patrol and Customs and Border Protection agencies appear to have used excessive force in the Friday confrontation. It said it was trying to establish contact with the Mexican man's family.

Border Patrol spokesman Daryl Reed said the man was taken to a San Diego-area hospital Friday night at the San Ysidro border crossing separating San Diego and Tijuana, Mexico. Reed says the man had become combative.
